Forget\u00a0great white sharks\u00a0and\u00a0grizzly bears, insects are actually the most dangerous group of animals in the world to humans.\n<p>This is in a large part due to their proficiency at carrying and spreading deadly diseases, from malaria to the black death.\n</p><p>Many species of insect feed on vertebrate\u00a0blood, putting them in a prime position to carry nasty bacteria, viruses, and parasites from victim to victim, and often from animal to human.\n</p><p>This list of deadly insects will cover such disease carriers, as well as those that can kill through toxic stings and bites, and even by destroying our crops.\n</p><p>Insects have been implicated in major history-defining events, from devastating plagues to colonial expansions, and their effects have shaped our own human evolution.

It has however been used in the past as a folk medicine, thought to be effective against warts and even rabies, but most commonly as an aphrodisiac.\n</p><p>In the past, it has been a major ingredient in \u201clove potions\u201d. This was a risky business, however, as the toxin can still kill in high enough quantities. In the 1950s a man was imprisoned for the deaths of two women whom he had given cantharidin-laced candies to in order to seduce them.\n</p><h3 class='\"wp-block-heading\"'><strong>9.

This is because in special circumstances they can gather in numbers of a biblical scale, moving across landscapes engulfing fields and devastating crops in a matter of minutes.\n</p><p>These swarming phases, which turn the normally solitary insect into a mass of millions, are triggered by a dry spell followed by rapid rainfall and vegetation growth. The drought forces them together onto the remaining areas of vegetation and the rainfall and subsequent abundance of food allows them to breed rapidly \u2013 creating a perfect storm. The major agricultural damage such swarms can cause can lead to famine and consequently many human fatalities.\n</p><h3 class='\"wp-block-heading\"'><strong>8.
